Description

[Detailed description of the invention] This invention relates to an attachment for electric hair clippers.

Conventionally, when hair is styled using electric clippers, an attachment with comb teeth is detachably attached to the electric clipper, and the distance between the comb teeth and the shearing blade of the electric clipper is set appropriately to achieve a desired cutting height. is being carried out.

There are various mounting directions for attaching such an attachment to an electric clipper, for example:
There is a device in which a leaf spring is attached to the attachment, and the elasticity of the leaf spring causes the engaging portion of the attachment to elastically engage with the engaging portion of the electric hair clipper.

However, in conventional devices with this structure, the leaf spring is attached to the attachment by welding or screwing, making the attachment work time-consuming.

This idea was devised in view of these points, and the purpose is to provide an attachment for electric hair clippers that makes it extremely easy to attach the leaf spring to the attachment, and that also reliably prevents the leaf spring from falling off. It is something to do.

This invention provides a semicircular attachment along the lower surface of the clipper body, forms a retaining part that removably engages both sides of the clipper body and both side edges of the attachment, and has a radius of curvature of the attachment. The ends of the semicircular leaf spring curved with a radius of curvature smaller than The spring is expanded and locked in the locking portion, so that the leaf spring can be prevented from being attached or detached.

An embodiment of this invention will be described based on the drawings.

First, at the tip of the hair clipper body 1, there is a shearing blade 4 consisting of a fixed blade 2 and a movable blade 3 that slides back and forth in contact with the upper surface of the fixed blade 2.
is provided.

A linear slide frame 5 that also serves as a decorative frame is formed on both sides of the front part of the hair clipper body 1, and a plurality of concave stopper receivers 6 for adjusting the hair cutting height are formed on this slide frame 5. It is said to be a joint.

Next, an attachment 8 having comb teeth 7 formed at its tip and having a semicircular cross-sectional shape on the lower surface of the hair clipper body 1 is provided.

On both side edges of this attachment 8, inclined parts 9 which are inclined outward from the inner circumferential surface in the expansion direction are formed over the entire length, and on both side edges far below these inclined parts 9, the above-mentioned A linear slide groove 10 into which the slide frame 5 is fitted is formed.

A convex stopper 11 is formed in this slide groove 10 and serves as an engaging portion to be engaged with the stopper receiver 6 .

Furthermore, a slide rib 13 is formed protruding from the bottom of the inner circumferential surface of the attachment 8 and is fitted into a slide groove 12 formed on the lower surface of the clipper main body 1 in the front-rear direction.

Further, a triangular guide rib 14 that is located outwardly from the slide rib 13 and serves as a deformation fulcrum is formed protrudingly on the inner circumferential surface of the attachment 8.
The apex is rounded by a small circular arc, and this apex is joined to the outer circumferential surface of the hair clipper body 1.

Moreover, the center part of the bottom surface of the attachment 8 is a pressing part 8.
It is said to be a.

Furthermore, the above is the idle rib 14 and the slide rib 13.
A plate spring locking groove 15 is formed along the circumferential direction on the inner circumferential surface of the attachment 8 adjacent to the plate spring locking groove 15, and both sides of the plate spring locking groove 15 reach a position close to the stopper 11. A leaf spring locking hole 16.17 is formed in the part to pass through the attachment 8, and a plate spring locking hole 16.17 with a different level with a recessed outer peripheral surface is formed at the upper edge of these leaf spring locking holes 16.17. Sections 1B and 19 are formed.

The leaf spring locking portion 15 has pressing portions 20.21 bent in an L shape at both ends and engaging the leaf spring locking portions 1B and 19.
A leaf spring 22, which is curved with a radius of curvature smaller than the radius of curvature of the inner circumferential surface of the attachment 8, is attached while being expanded and biases both side edges of the attachment 8 toward each other.

In addition, a hair escape hole 23 is provided in the bottom of the attachment 8.
is opened, and the bottom surface of the outer circumferential surface of the attachment 8, which is the back side of the mounting position of the leaf spring 22, has a plurality of protrusions formed to protrude at a slight height in the left-right direction. A non-slip portion 24 is formed.

In such a configuration, when attaching the attachment 8 to the clipper body 1, the attachment δ is positioned on the lower surface of the clipper body 1 and pushed up.

As a result, the slide frame 5 fits into the slide groove 10,
Furthermore, since the inclined portions 9 are formed on both side edges of the attachment 8, this fitting is performed extremely easily.

Furthermore, the slide rib 13 fits into the slide groove 12,
The apex of the guide rib 14 joins to the outer peripheral surface of the clipper body, and attachment of the attachment 8 to the clipper body 1 is completed.

When pushing up the attachment 8, the attachment 8 expands outward, but after the slide frame 5 fits into the slide groove 10, the diameter of the attachment 8 contracts inward due to its own elasticity, especially the elasticity of the leaf spring 22. The fitting becomes reliable.

Through this fitting, the stopper 11 engages with the stopper receiver 6, so that movement of the attachment 8 in the front-rear direction is fixed.

Moreover, the movement of the attachment 8 in the circumferential direction is fixed by the fit between the slide frame 5 and the slide groove 10 and the fit between the slide rib 13 and the slide groove 12.

Furthermore, since the apex of the guide rib 14 is joined to the outer circumferential surface of the hair clipper body 1, movement of the attachment 8 in the front-rear direction and circumferential direction is even more reliably prevented, so that the fixed state of the attachment 8 is extremely stable.

By fixing the attachment 8 to the clipper body 1, the distance between the comb teeth 7 and the shearing blades 4 is determined, and the hair cutting height is determined.When attaching the attachment 8 to the clipper body 1, the stopper 11 can be Stopper receiver 6
By adjusting the position to engage with the attachment 8, it is possible to set the hair cutting height to a desired height at the same time as attaching the attachment 8.

However, since it is quite difficult to align the position in this way, the attachment 8 is attached to the clipper body 1.
It is better to change the hair cutting height after installing it.

In this case, the anti-slip portion 24 is pressed against the clipper main body 1 side.

This pressing operation causes the slide rib 13 to move into the slide groove 1.
The guide rib 14 is pressed against the pressure part of the clipper body 1.
slides outward while bonding to the outer peripheral surface of the

Moreover, since the apex of the guide rib 14 is rounded, it slides extremely smoothly, and even if the joint part of the guide rib 14 moves after sliding, the state of joint with the outer peripheral surface of the clipper body 1 is maintained in the same way as the sliding surface. be done.

As the guide rib 14 slides, both side edges of the attachment 8 expand outward, and the stopper 11 and the stopper receiver 6 are disengaged from each other, and the slide groove 10 and the slide frame 5 are disengaged from each other.

By disengaging the stopper 11 from the stopper receiver 6, the attachment 8 becomes movable in the front-rear direction, and from this state, the non-slip part 24 is pushed toward the clipper body 1 side and biased in either the front-rear direction. Then, the attachment 8 slides in the urging direction, the distance between the comb teeth 7 and the shearing blade 4 changes, and the hair cutting height is adjusted.

Then, when the stopper 11 is positioned facing any stopper receiver 6 and the finger is released from the anti-slip part 24, the attachment 8 uses its own elasticity, especially the elasticity of the leaf spring 22, to move the top of the guide rib 14 to the clipper body. The slide frame 5 fits into the slide groove 10 and the stopper 11 engages with the stopper receiver 6 to set the new hair cutting height. Ru.

Note that when the attachment 8 is slid in the front-rear direction, the slide rib 13 fits into the slide groove 12, so that the attachment 8 is prevented from moving in the circumferential direction.

In addition, by forming the anti-slip part 24, the thickness of the attachment 8 in the area where the anti-slip part 24 is formed is made thinner, increasing the elasticity of the attachment 8 and reinforcing the attachment 8. It prevents your fingers from slipping when biasing in the front-back direction.

Note that after the slide groove 10 and the slide frame 5 are fitted together and the stopper 11 and the stopper receiver 6 are disengaged, the clipper main body 1 must be slightly rotated in the direction in which the slide frame 5 intersects the slide groove 10. For example, even if the finger is removed from the anti-slip portion 24, the slide frame 5 does not fit into the slide groove 10, and the attachment 8 can be easily removed from the clipper body 1.

When attaching the leaf spring 22 to the attachment 8, as shown in FIG. If the leaf spring 22 is aligned with the inner peripheral surface of the attachment 8 and the other pressing part 21 is slid toward the other leaf spring locking hole 17, the pressing part 2
1 easily engages with the leaf spring locking portion 19, and the pressing portion 20 also engages with the leaf spring locking portion 18.

Therefore, the leaf spring 22 can be easily attached without screwing or welding, and the number of parts and manufacturing steps can be reduced.

Furthermore, the pressing parts 20 and 21 are arranged at different levels in the leaf spring locking part 18.
, 19 while urging both side edges of the attachment 8 in a direction closer to each other, the leaf spring 22 is reliably prevented from wobbling or falling off.

A part of the hair sheared by the shearing blade 4 passes through the lower surface of the clipper body 1 and is discharged from the escape hole 23, and the remaining hair naturally falls from the upper surface of the clipper body 1.

Therefore, sheared hair does not accumulate on the top side of the clipper body 1 and the top of the shearing blade 4, and subsequent hair is smoothly guided to the shearing blade 4, so that the cutting edge of the shearing blade 4 is always in a good state. It is maintained.

As mentioned above, this invention forms locking parts on both side edges of the attachment, and by locking both ends of the leaf spring to these locking parts, the leaf spring can be easily attached to the attachment. Since the leaf spring is expanded and its end is locked in the locking part, the installation state of the leaf spring is secure and the leaf spring can be prevented from wobbling or falling off. This has the effect of ensuring that the attachment is securely secured.
